Sound card recommendations?

I'm building a little P5/200 box for my kids to play Reader Rabbit (which
unfortunately runs only under Windows - Wine can't handle it) and am trying
to decide whether to:
1) Buy a cheap sound card for it, or
2) Give them my old ENS1371 from my workstation and upgrade to something
newer.
I use ALSA for sound. I almost never game, so all I really need is
something that can play back a PCM stream decently. Now, my current card
works reasonably well. Is there anything that upgrading to a newer card
would get me? Better quality? More simultaneous sounds at once? Better
ALSA support with nifty features I can only imagine?
Any thoughts? Recommendations?
